The calculated value of t is greater than the critical value of t at alpha = 0.05 and degrees of freedom = 19. Therefore, we reject the null hypothesis and conclude that there is a significant difference between the resting pulse rate of college runners and the Olympic team's resting pulse rate of 60 beats per minute.
